ACS Materials Letters, Journal Year: 2022, Volume and Issue: 5(1), P. 60 - 78

Published: Dec. 1, 2022

Metal halide perovskites have attracted extensive attention in the field of photocatalysis, because their excellent photophysical properties, including high optical absorption coefficients, tunable band structures, and long carrier diffusion lengths. The application prospect conventional lead-based is restricted by toxicity instability issues. Therefore, it imperative to develop environmentally friendly stable lead-free (LFHPs) for photocatalysis. In recent years, rapid development LFHPs has provided new opportunities photocatalytic applications, ranging from solar-to-chemical energy conversion organic reactions. this Review, we summarize progresses with an emphasis on strategies available improve performance stability. Furthermore, present outlook future directions challenges emerging field.

Highly Emitting Perovskite Nanocrystals with 2-Year Stability in Water through an Automated Polymer Encapsulation for Bioimaging

ACS Nano, Journal Year: 2022, Volume and Issue: 16(9), P. 13657 - 13666

Published: Aug. 1, 2022

Lead-based halide perovskite nanocrystals are highly luminescent materials, but their sensitivity to humid environments and biotoxicity still important challenges solve. Here, we develop a stepwise approach encapsulate representative CsPbBr3 into water-soluble polymer capsules. We show that our protocol can be extended coated with different ligands, enabling an outstanding high photoluminescence quantum yield of ∼60% is preserved over two years in capsules dispersed water. demonstrate this on-bench strategy implemented on automated platform slight modifications, granting access faster more reproducible fabrication process. Also, reveal the exploited as photoluminescent probes for cell imaging at dose low 0.3 μgPb/mL well below toxicity threshold Pb Cs ions. Our contributes expanding significantly fields applications these materials including biology biomedicine.
